Crushing Plant Flowsheet DesignLayout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the cone crusher ...

Ball Grinding Process. Ball grinding process is a grinding method of crushing ore with ballshaped grinding medium in the grinding mill. In the ball grinding process, because the steel ball has 360° free rotation, it is suitable for falling motion and throwing motion. When the rotating speed of the cylinder is low, the medium rises to a ...
